[0027] Please refer to Figures 1 to 3 as shown, a high-precision cradle seat transfer device provided by an embodiment of the present application is used to solve the problems of low transportation efficiency and poor transportation accuracy in the prior art.
[0028] To achieve this purpose, the present application adopts the following technical solutions:
[0029] This application provides a high-precision cradle transfer device, which includes a first driving member 10, a bracket 20, a lifting assembly 30 and a push rod 40, where:
[0030] The first driving member 10 is fixedly installed on the bracket 20. The first driving member 10 includes a motor 11 and a first connecting shaft 12. The first connecting shaft 12 is placed along the first direction ( Figure 1 the X direction in the figure), and the motor 11 is configured to drive the first connecting shaft 12 to rotate;
[0031] The lifting assembly 30 includes a first connecting plate 31, a pulley 32 and a lifting member 33. One end of the first connecting plate 31 is fixedly connected to the end of the first connecting shaft 12. The first connecting shaft 12 is perpendicular to the direction where the first connecting plate 31 is located. The first connecting shaft 12 is configured to drive the first connecting plate 31 to rotate. The pulley 32 is rotatably installed at the other end of the first connecting plate 31 along a direction parallel to the first connecting plate 31. The pulley 32 can reciprocally slide in the lifting member 33 along the second direction ( Figure 1 the Y direction in the figure). The first connecting plate 31 drives the pulley 32 to slide in the lifting member 33, so that the first connecting plate 31 supports the lifting member 33 to reciprocate up and down in the vertical direction;
[0032] The push rod 40 is fixedly connected to the lifting member 33 in the vertical direction. The lifting member 33 is configured to drive the push rod 40 to perform synchronous lifting and lowering movements.
[0033] By driving the first connecting shaft 12 to rotate through the motor 11, the first connecting shaft 12 and the first connecting plate 31 rotate simultaneously. The first connecting plate 12 drives the pulley 32 to slide in the lifting member 33, so that the first connecting plate 12 supports the lifting member 33 to reciprocate up and down in the vertical direction. Thus, not only is it possible to drive the push rod 40 to perform synchronous lifting and lowering movements with the lifting member 33, facilitating the rapid short-distance transportation of items and improving the transportation efficiency, but also the structure is simple and easy to operate.
[0034] In one embodiment, the first connecting plate 31 and the pulley 32 are connected by a second connecting shaft 34. The second connecting shaft 34 is placed along the first direction. The first end of the second connecting shaft 34 is fixedly connected to the first connecting plate 31. The second end of the second connecting shaft 34 passes through the center of the pulley 32, and the pulley 32 is rotatably installed at the second end of the second connecting shaft 34.
[0035] By passing the second connecting shaft 34 through the first connecting plate 31 and the pulley 32, the first connecting plate 31 and the pulley 32 are connected. This not only realizes the rotation of the first connecting plate 31 to drive the pulley 32 to move, but also has a simple structure, facilitating operation and maintenance.
[0036] In one embodiment, the lifting member 33 includes an upper plate 330, a lower plate 331, and a second connecting plate 332. The second connecting plate 332 is configured to connect the upper plate 330 and the lower plate 331. A first sliding groove 333 is formed at the lower end of the upper plate 330 along the second direction, and a second sliding groove 334 is formed at the upper end of the lower plate 331 along the second direction. The first sliding groove 333 and the second sliding groove 334 correspond to each other in the vertical direction.
[0037] Through the cooperation of the first sliding groove 333 and the second sliding groove 334, on the one hand, it provides guidance for the movement of the pulley 32 within the lifting member 33, and on the other hand, it also limits the position of the pulley 32 to prevent the pulley 32 from deviating.
[0038] In one embodiment, the bracket 20 includes a top plate 21, a bottom plate 22, and a plurality of vertical plates 23. The vertical plates 23 are vertically arranged, the bottom plate 22 and the top plate 21 are perpendicular to the vertical plates 23, and the lifting member 33 is located between the top plate 21 and the bottom plate 22.
[0039] Through the cooperation of the top plate 21, the bottom plate 22, and the plurality of vertical plates 23, on the one hand, it enhances the overall structure and makes the whole more stable, and on the other hand, it facilitates the integration of other components on the bracket 20, making the overall structure more compact, saving space, and making the operation more convenient.
[0040] In one embodiment, a plurality of guide rods 24 are vertically arranged between the top plate 21 and the bottom plate 22. The guide rods 24 pass through the lifting member 33 and are respectively fixedly connected to the top plate 21 and the bottom plate 22 at both ends. The guide rods 24 are configured to provide guidance for the movement of the lifting member 33.
[0041] By passing a plurality of guide rods 24 through the lifting member 33, on the one hand, it supports the top plate 21 and the bottom plate 22, improving the stability of the overall structure, and on the other hand, it provides guidance for the movement of the lifting member 33 to ensure that the lifting member 33 maintains the correct direction and position when moving up and down.
[0042] In one embodiment, guide rails 25 are vertically arranged on the vertical plates 23. The guide rails 25 are configured to support n detection members 26 (n is a positive integer not less than 2).
[0043] By arranging the guide rails 25 on the vertical plates, on the one hand, it provides support for the n detection members 26, and on the other hand, it facilitates the adjustment of the distance between two adjacent detection members 26, so as to meet the lifting members 33 with different transportation distances, improving the compatibility of the equipment.
[0044] In one embodiment, the guide rod 24 is connected to the lifting member 33 through a sliding sleeve 27, and the sliding sleeve 27 can slide along the guide rod 24.
[0045] By arranging a sliding sleeve 27 between the guide rod 24 and the lifting member 33, it not only avoids the direct contact between the guide rod 24 and the lifting member 33, which may cause mutual friction and damage, but also reduces the friction between the guide rod 24 during the sliding process, making the lifting member 33 operate more smoothly and improving the transportation efficiency.
[0046] In one embodiment, n detection members 26 are installed on the guide rail 25 and can slide along the guide rail 25. The detection members 26 are configured to detect whether the lifting member 33 reaches a preset position.
[0047] By arranging the detection members 26, it is possible to detect and feedback whether the lifting member 33 reaches the preset position, and through the cooperation of two adjacent detection members 26, the running distance of the lifting member 33 can be detected, ensuring the accuracy of transportation.
[0048] In one embodiment, the end of the ejector rod 40 passing through the lifting member 33 is provided with a thread, and there is a tightened nut 41 on the thread.
[0049] Through the cooperation of the thread and the nut 41 at one end of the ejector rod 40 passing through the lifting member 33, on the one hand, the ejector rod 40 is further fixed on the lifting member 33 to ensure the stability of the ejector rod 40 during operation. On the other hand, by adjusting the position of the nut 41 of the ejector rod 40, the up and down movement range of the ejector rod 40 can be controlled to ensure that the product can move up and down accurately during the automated production process.
